Ecophysiology represents the study of short-term acclimation and long-term adaptation of plants to changing environmental conditions. Understanding of these basic physiological processes and their response to biotic and abiotic stress is crutical for plant production. These includes photosynthesis, respiration, transpiration, water and mineral uptake. The analyses is based on measurements of ecophysiological parameters like leaf gas exchange, chlorophyll fluorescence, water-use efficiency, plant water status, and chemical analysis of plants and soils in controlled greenhouse experiments and field trials. The research range from physiological processes inside the plants to studies on soil-plant interactions within natural and agricultural ecosystems. A key question is the integration of plant ecophysiology into ecosystem functioning.  

The research is grouped in five main topics:

(i)    physiological and morphological adaptations

(ii):   photosynthesis and carbon allocation

(iii)   mineral nutrition of higher plants

(iv)   stress physiology 

(v)   root systems and growth performance

Tree ecophysiology

It is crucial to understand growthl responses of trees to climate variability and soil conditions. Therefore, more detailed ecophysiological informations are required. In this context, a research focus are ecophysiological adaptations of pionieer trees on marginal lands and reclaimed post-mining-sites. Read more


Environmental physiology in deserts

Plant physiology is the study of how plants acquire resources such as water and nutrients in order to conduct photosynthesis that is necessary for plant growth, reproduction and survival. Read more...
